During the sixth Friday of demonstrations near the Gaza Strip, 40 Palestinians, including three journalists, were injured after burning kites intended to be used to start fires in Israel were used as part of the protests, USA Today reported.

Israel’s military had warned against burning kites after a number of wildfires were started a day prior.

“Rioters are flying kites with burning items, intending to ignite fires in Israel,” the Israel Defense Forces said on Twitter. “Also, rioters hurled an explosive device at IDF troops who are responding with riot dispersal means [and] fire in accordance with the rules of engagement.”

Palestinian leaders also seek the “right of return” for some 750,000 Palestinian refugees who were driven from their homes in what is now Israel.

“If Palestinian refugees decide one day to break through the fence and enter Israel en-masse, that is their legal and principled right, but we have no intention of doing that in the campaign’s first phase,” Artima told Ynet in the beginning of April

The demonstration was intended to be non-violent civil disobedience, likened to the acts of Mahatma Gandhi and Martin Luther King Jr.

Thousands of men, women and children are currently gathered in tents along with border fence, and have since been joined by militants who have encouraged violence. Tires have been burned close to the fence, stones hurled over and gasoline bombs are tossed toward Israeli soldiers stationed on the other side.
